*1 If your boot kernel is located on your hard drive, and your hard drive fails, you will get the Flash ROM error instead of the hard drive error because the boot kernel could not be loaded.

*2 It may be possible to recover from a Flash ROM error by pulling out the power cord and trying to boot again the next day.

*3 Users have reported getting this error when the hard drive already has a Linux partition on it. The solution appears to be to simply reformat the hard drive.This might also happen if the PSU does not provide enough power for the hard drive, or if the hard drive takes too much time spinning up.
